| 18 | .SH DESCRIPTION | |
| 19 | .B getln2 | |
| 20 | reads a line of characters, terminated by a | |
| 21 | .I sep | |
| 22 | character, | |
| 23 | from | |
| 24 | .IR ss . | |
| 25 | ||
| 26 | The line is returned in two pieces. | |
| 27 | The first piece is stored in | |
| 28 | .IR sa . | |
| 29 | The second piece is | |
| 30 | .IR cont , | |
| 31 | a pointer to | |
| 32 | .I clen | |
| 33 | characters inside the | |
| 34 | .I ss | |
| 35 | buffer. | |
| 36 | The second piece must be copied somewhere else | |
| 37 | before | |
| 38 | .I ss | |
| 39 | is used again. | |
| 40 | ||
| 41 | If | |
| 42 | .B getln2 | |
| 43 | sees end-of-input before it sees | |
| 44 | .IR sep , | |
| 45 | it sets | |
| 46 | .I clen | |
| 47 | to 0 and does not set | |
| 48 | .IR cont . | |
| 49 | It puts the partial line into | |
| 50 | .IR sa . | |
| 51 | ||
| 52 | .B getln2 | |
| 53 | normally returns 0. | |
| 54 | If it runs out of memory, | |
| 55 | or encounters an error from | |
| 56 | .IR ss , | |
| 57 | it returns -1, | |
| 58 | setting | |
| 59 | .B errno | |
| 60 | appropriately. | |
